Specification of Letters Patent.

Application filed December 80, 1911.

Patented Oct. 13, 1914.

Serial No. 668,593.

To all whom it may concern:

Be it known that I, FREDERICKYA. FELD- KAMP, a citizen of the United States, residing at Newark, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in Radiators; and I do hereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper tains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

The present invention has reference, generally, to improvements in radiators adapted to be used in heating systems; and, the present invention has for its principal object to provide a simple, cheap and novel construction of heating radiator of high efliciency, the several parts of which are constructed and arranged in such a manner sq as to proyide a very high percentage of heat radiation.

Another object of the present invention is to provide a sightly and compact construction of radiator, which is greatly reduced in weight, and which is easily and cheaply manufactured.

Other objects of the present invention not at-this time more particularly enumerated will be clearly understood from the following detailed description of the present invention.

With the various objects of the present invention in view, the said invention consists, primarily, in the novel radiator for heating systems hereinafter set forth; and, the invention consists, furthermore, in the novel arrangements and combinations of the various devices and parts, 'as well as in the details of the construction thereof, all of which will be more fully described in the following specification, and then finally embodied in the clauses of the claims which are appended to and which form an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a radiator made according to and illustrating one embodiment of the principles of the present invention; Fig. 2 IS a horizontal section of the same, said section being taken on line 22' in said Fig. 1 looking in the direction of the arrow m; and Fig. 3 is a longitudinal vertical section of the same, said view being drawn upon an enlarged scale.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference-character 1 indicates a complete radiator for heating sys tems made according to and illustrating one embodiment of the principles of the present invention, the same comprising a suitable base-member 2 having supporting lugs 3 suitably connected therewith in any desirable manner. Connected with said base member 2, and preferably forming an integral part thereof, is an intake-member 4, providing an inlet passage 5. Said intakemember 4 is internally screw-threaded at each end, for the connection therewith at its 'outer end, of a service-pipe 6, and for the connection with its inner end of a battery of radiator-plates of the general arrangement and construction to be presently more 7. Connected with said base-member 2, and

suitably supported thereon, is a suitably formed casing or shell, as 8, the same being preferably. constructed of sheet-metal, and the parts of which are suitably arranged and assembled so as to form the said casing or shell 8. Connected with the upper end of said casing or shell 8 is a top-plate or cover, as 9, which may be made in a suitable ornamental form and design, and the body of which is provided with perforations of any desirablefancy or ornamental grill-work provided with suitable openings, as 10, communicating with the interior of said casing or shell 8.

The reference-character 11 indicates a header-pipe which may be externally screwthreaded upon its lower end-portion, so as to be screwed into the inner end of the said inlet-passage 5, said header-pipe being closed at its upper end by means of a suitable cap 12. Extending longitudinally across the lower portion of the interior of said shell or casing 8 are a plurality of racombed shell, suitably formed by the facewalls .14 and the edge walls 15. The said face-walls 14 of said hollow shells are provided with a multiplicity of oppositely disposed openings of any desired configuration, and within the space, between the said face walls 14; and surrounding each opening, are thin walls 16, said walls being arranged in close proximity to each other, so that in addition to forming by means of said openings a multiplicity of open air-passages 17, the said walls will also form tubular or hollow and interconnected passages 18 within said shell, through which the heat-carrying fluid may be distributed. Said shells which form said radiator-plates or sections 13 are provided, preferably, at each end, with tubular members 19 which provide entrances and exits, respectively, to and from the said radiator-plates or sections for causing the heating medium or fluid to circulate therethrough, and to pass into a second headerpipe 20. The said header-pipe 11 is provided with suitably disposed openings in which are received one of the pair of tubular members 19 of each radiator-plate or section 13, whereby the same are properly connected with said header-pipe and established in communication with the service-pipe 6, said tubular members 19 being secured in such connection by means of solder or in any other suitable manner. Arranged within said shell or casin 8, and preferably supported upon said base-member 2, is the said second header-pipe 2O herein-above mentioned, said pipe having suitably disposed openings in which are received the other oppositely placed tubular members 19 of the said radiator-plates or sections 13; and, whereby the same are properly connected in communication one with the other. The tubular members 19 are secured in such connection, by means of solder, or in any other desirable manner. The arrangement of said radiator-plates or sections 13, between the respective header-pipes 11 and 20, is made in such a manner, so as to produce an inclination or slope of the said radiator-plates or sections, to permit of a proper drainage or clearance of the same of any condensation of the heating medium or fluid passed therethrough. Said header-pipe 20 is also provided upon its upper end with a perforated cap 21, with which is suitably connected the one end of avent-pipe 22, which extends through said shell or casing 8, and terminates in a suitably formed and automatically operating or other suitable relief or escape-valve, as 23, so that upon the entrance of the heatin fluid into the said radiator-plates or sections 18, the air may be easily and quickly driven forth to provide for a free and uninterrupted circulation of the heating medium or fluid, as will be evident.

heated within said casing or shell 8 by the said radiator-plates or sections 13, the heated air passing upwardly and out of the openings 10 in the topplate 9 of said shell or casing 8. The preferred method of manufacturing said radiator-plates or sections is to produce the same by means of an electrolytic process, whereby each plate or section is made in the form of a-hollow honeyconibed integral shell embodying all the features herein-above mentioned, thus providing a plate or section of thin metal and large area of radiating surface, whereby the heat of the heating medium or fluid delivered into said plates or sections is readily and quickly given off, and communicated to the air surrounding the radiator-plates or sections. The number of said radiator-plates or sections for a complete radiator made according to the principles of this invention may be varied as desired, and may be more or less than shown in the accompanying drawings, according to the heating capacity desiredin any single radiator, all of which will be clearly understood. The heating medium or fluid may be delivered to said radiator through the service-pipe 6, and thence distributed through the radiatorplates or sections 13, the walls of which are thin, and owing to the honey-combed construction providing a great area of radiating surface, whereby a large percentage of the heat may be given off, and through the operation of the radiator caused to warm the surrounding air, in a very simple and efiicacious manner.

In the drawings, I show a shell or casing 8 of considerable height in comparison to the height of the plurality of radiator-plates or section, so that the upper portion of said shell or casing provides a spacious reservoir of heated air, and likewise produces a great draft; but, I do not wish to be understood as limiting the present invention to such construction, as the height of the shell or casing 8, in proportion to that of the combined radiator-sections or plates contained therein may be varied to any degree, either higher or lower than shown, according to the particular exigencies or needs of the use or manner of using the radiator in practice.

I claim 1. A radiator comprising a base-member provided with an intake-member forming aninlet-passage for a heatingfiuid,saidbasemember being further provided with openings forming air-passages, a casing supported upon said base-member, a top plate provided with openings forming air-passages connected with said casing, a plurality of hollow honey-combed radiator-plates arranged within said casing, means for interconnecting said radiator-plates, and means for connecting said radiator-plates with said heating fluid inlet-passage.
